Internet of Things: Attacks and Defences

Ever since the introduction of IoT, it has gained much popularity and is being widely used nowadays. However, assimilation of these everyday objects also introduced many security threats, which have become a matter of concern among the research fraternity. Unfortunately, the security threats and their corresponding countermeasures are not well organized in the context of IoT. Therefore, through this survey, we attempt to provide a list of attacks in each layer of IoT, suggested countermeasures in literature and possible research direction in the area.
